为确保纸机的正常运行、无故障转换以及产品的高质量,必须在备浆过程中除去二次纤维浆料中的胶粘物。然而,由于浆料中胶粘物类型繁多,因此很难评估所采用的胶粘物去除方法的去除效率。即使传统的“大胶粘物和阳离子需求量”的测试项目也不能评估生产过程中潜在的胶粘物问题。该文研究新闻纸厂胶粘物整体特征的新方法由“大胶粘物”、“微胶粘物”以及“二次胶粘物”的检测项目组成,它们的检测意义分别是:“大胶粘物”能够检测生产工艺中的去除效率;“微胶粘物”和“二次胶粘物”能预测在不同条件下浆料的沉积潜能(“微胶粘物”可预测钙皂沉积物,“二次胶粘物”可预测溶解和胶体物质的不稳定性)。
To ensure proper operation of the paper machine, trouble-free switching and high product quality, it is necessary to remove stickies in the secondary fiber slurry during stock preparation. However, it is difficult to evaluate the removal efficiency of the applied stickies removal method because of the wide variety of stickies in the slurry. Even the traditional test items “Large Adhesives and Cation Demand” can not assess potential stickies in the manufacturing process. The new method of studying the overall characteristics of newsprint mills is composed of testing items such as “big glue”, “micro glue” and “secondary glue”, and their detection significance They are: “Big Glue” to detect removal efficiency in the manufacturing process; “Micro-Glue” and “Secondary Glue” predict the deposit potential of the slurry under different conditions ( “Micro-stickies ” can predict calcium soap deposits, “secondary stickies ” predictable dissolution and colloidal material instability).
